Determination of kinetic transport coefficients for ions in air as functions of electric field and temperature

A method for determining the kinetic coefficients of ion transfer in gases, viz., mobility K and longitudinal (D-L) and transverse (D-T) diffusion coefficients, as functions of the electric field E and gas temperature T is described. The method is based on the measurement of the increments to the ion mobility coefficients as functions of the electric field at a parametrically specified temperature. The kinetic transport coefficients K(E, T) and D-L,D-T(E, T) are determined for positive ions of aniline, pyridine, benzene, orthotoluidine, dimethyl methyl phosphonate, N-methyl aniline, N,N-dimethyl aniline, N,N-diethyl aniline, and diphenyl amine (DPA) formed as a result of beta-ionization in air.
